[EKS controller]: can't create a node group

[gecube]

Hello!

I tried to use the next manifest

apiVersion: eks.services.k8s.aws/v1alpha1
kind: Nodegroup
metadata:
  name: production-fix-ng-20241010-b
  namespace: infra-production
spec:
  name: production-fix-ng-20241010-b
  clusterName: production
  diskSize: 100
  subnetRefs:
    - from:
        name: production-private-eu-west-2b
  nodeRole: arn:aws:iam::****:role/*****
  scalingConfig:
    minSize: 1
    maxSize: 1
    desiredSize: 1
  instanceTypes:
    - m5.large
  taints:
    - key: node-role.kubernetes.io/fix
      value: ""
      effect: "NO_SCHEDULE"
  labels:
    node-role.kubernetes.io/fix: ""
  amiType: BOTTLEROCKET_x86_64

I am getting the next error in the status:

          },

      message: Resource not synced
      reason: resource is in terminal condition
      status: 'False'
      type: ACK.ResourceSynced

It is very ambiguous error and does not give me any information about what is wrong.

It helped to remove the label, but it is really strange as in the doc there are no restrictions:
